# -*- coding: utf-8 -*- class person:
def one( self ,name,age):
print "you name is %s and you age is %s." % (name, age)
p = person() #绑定实例
p.one( "du" , 22 )
|
执行结果:
1
|
you name is du and you age is 22.
|
其实self可以不必写成self,但是必须要有一个参数如下图
详细了解可以参考博客:http://www.cnblogs.com/jessonluo/p/4717140.html
二,__init__初始化。

# -*- coding: utf-8 -*- class person:
def __init__( self ,sex):
self .sex = sex
def one( self ,name,age):
print "you name is %s and you age is %s and sex is %s" % (name, age, self .sex)
p = person( "boy" ) #绑定实例
p.one( "du" , 22 )
|
执行结果:
1
|
you name is du and you age is 22 and sex is boy
|
其实就相当于变量sex在类里。比函数大一级别。如下面的程序,和上面的执行结果是一样的。

p = person( "boy" ) #绑定实例
p.one( "du" , 22 )
